This inventionv relates 'to-container machinery and relates more `particularly to a combination lining and edge lfinishingmachine for the making of flatcontainers- -.'I?hemachine of the present-invention hasV specialusefulness in the making of envelope type containers for phonograph records. Withcthe adventof vthe long playing record the record albums` are seldom used since the single records taketh@ place-of the .pluralrecords yand each recordlis sold Yin .the single envelope. The .containerfincludesr one wallwformed of relatively heavywcardboard.V anda. second wall of paper. three, edgesof .which 'are .glued to the outer surface of the heavier lwall, leaving the fourth edge open fonthel introduction of the record. This latter Wallis then covered bya label of the same size as the wall so., that the folded-in edges are coveredas- Well. The machineof the present invention has no reference .to thelabel applying operation. Y

An important object of the present invention -is-to provide a machine of the character described which accurately folds the aforesaid three edges of the paper blank around the edges ofthe cardboard wall and then presses such edges, to which adhesive material has previously beenvapplied firmly against the opposite faceof the wall so that the adhesive bond is effective and comlete.

p. Another object of the invention is to provide an edgefinishing machine which may be operatedsubstantially continuously and wherein the only limitation on its speed of operation is that of speed of the operator who feedsy the superimposed blanks to the machine. y

A further object of the invention is to provide improved folding members for bending rdownwardly the upstanding edges of the blank just beforethey are introduced to the rollers which apply the final pressure.

The application of the second wall to the rst wall is essentially a lining operation even though adhesive is applied only to the flaps which are fo11dedpressed landflnished by the machine. In the drawings: Y l y Fig. 1 is a plan view of the machineembodying the present invention; v

A v (c1. 93-62) 2 f Fig. 5 is a brokentop rollers removed;

Fig. 6 is a broken section taken on linep-G-f-G of Fig. 5; f

Fig. 7 is a broken section taken on line 'I'-*I- OfFig.5; Fig. 8 is a broken section taken on line 8-'48 of Fig. 1; Y Fig. 9 is a broken perspective view of the fold-- ing member. f f The operative parts of the machine are mounted on or -suspended from atop plate VIII- which is supported on Vlegs II.r `Side frames I2 and I3 are mounted in spaced relation on the top plate. Shafts I4 and I5 which carry two lower rollers I5 and Il are-journaled for rotation above the top plate. yBearings 'I8 Yfor: shaft I4 lare mounted on the side plates. An upper roller 22` is mounted on shaft '2I'and the bearings for shafts I5 and 2l are mounted on the top plate.l These shafts are disposed on fixed axes Yand a second upper roller 23 is mounted on'shaft 24.' This shaft is journaled in arms 25 and 26.y The opposite ends of these arms are journaled in stub shafts 21 and 28 and roller 23 is thus swingable fromanupper to a lowered position. i

Only shafts I4 Yand I5.are driven, driving being effected byfa drive chain 3I (Fig. 4).which engages sprockets 33 and v32 keyed to such shafts. The chain also engages an idlerV 34 onshaft 35 and drive sprocket f3.6 keyed todrive shaft 31- `iournaled in brackets 4I.

Rollers I6, I1 and 22, which may be formed from rubber or other resilient material, are of cylindrical shape whereas roller 23 has spaced annular recesses 42.

The work 43 (Fig. 2) is supported on a platen 44, the frontend of which is mounted by means of a bracket 45 carried on a-xed shaft 46 sup ported at its ends by brackets 41 secured to side frames I2 andl3.

Y The ,other end of the platen is supported by a post 5I mounted atits .lower end in top plate I0; For the purpose oflocating :the work at the front of the machine an angle bracket 52 is provided which is movable ,forwardly or rearwardly to. an adjusted fixed position Where it is secured by a screw 50.- To swing arms 25 and 26 downwardly, stub shafts 2l and 28 are provided with gears 53 and 54, keyed thereto and these gears are ven-` gaged by toothed racks 55 and 56A mounted for sliding vertical movement inthe frame. YAt their lower endsthe racks are pivotally secured at59 to onerend of levers 6I) and 6I, the opposite ends of the levers being pivoted to the frame `at .-62.

l Ip'he arms vand, the racks are moved vdcwvnwardly plan viewfwith` oneof the by cams 63 and 64 keyed to shaft 66. A roller 61 on each arm engages the outer periphery of the cam.

Shaft 66 is journaled in bearings 10 and is driven by means of a sprocket 1I freely carried thereon and a drive chain 12 which engages an idler 13 and is driven by a sprocket 14 keyed to drive shaft 31. This drive shaft is rotated by a motor (not shown) which may have a chain drive leading to sprocket 69 keyed to shaft 31, and during operation of the machine rollers I6 and I1 rotate continuously. Rotation of shaft 66 is discontinuous, however, and for this purpose a one-revolution clutch assembly is interposed between constantly rotating sprocket 1|, freely carried on shaft 66, and suchshaft. This comprises a notched gear 15 which rotates conjointly with sprocket 1| and a dog 16 pivoted at 11 on...

disc 18 keyed to shaft 66; When projection 80 on dog 16 enters a notch in gear 15, sprocket 1| drives shaft 66 and cams 63 andvfl-through one revolution, thus drawing racks 55 and 56 downwardly, and swinging arms 25 and 26, carrying front upper roller 23 down to operative position against the work, and then up again for the next cycle of operation. j

The contour of cams 63 and 64 is such as to retain roller 23 in this downward position for a suicient period to enable it to engage the work until its. trailing edge has passed the forward rollers. Racks 55 and 56 are positively driven only downwardlyand return movement is effected by springs 8| secured at one end to arms 25 and 26 and atv the other to xed brackets 62 carried by the frame'. Thus, rollers 61 are fast against the outerr peripheries of cams 63 and 64 at all times. Y

The manual control for the one-revolution clutch assembly will now be described. Dog 16 is urged at all times` in the direction of notched gear 15 by spring 83. It is normally held out of such engagement by lever-84 centrally pivoted at 85. A spring 86urges lever 84 in a counter-clockwise direction (Fig. 3).

A foot treadle 9.0 is keyed to shaftgl journaled between legs I I, and a link 92 also keyed to Ysuch shaft is connected at 93 to lever 94 suitably mounted` for vertical reciprocating. movement. The latter is formedwith ashoulder- 91 which supports the` front terminalof lever 84. The upper end of lever 94 isbevelle'dV aty 95Y and'is arranged to contact. fixed diagonal surface 96. Thus, when the treadle is depressed leverk 94 moves; upwardly actuating lever 84 and freeing the clutch assembly for rotation. Simultaneously, the upper end ofv lever 94 travels in the direction of the operator, thus freeing lever 84 -to return to the position of Fig. 3Y so as to disengage the. dog after itsone-revolution travel. 98 limits rotation of lever 84 due to action of spring'86 and when treadle 90 is released, either before orafter the one revolution, spring |00 returns lever 94 to the position of Fig. 3.

A word about the work 43 is in order at this point. The cardboard wall |0I is usually square and is uppermost. The paper blank |02 forming the other wall of the envelope hasa forward edge or flap |03 and opposed -edges or flaps |04 on two sides, The fourth or trailing edge of blank |02 is coextensive with the adjoining edge of blank IOI.. Another machine has'applied adhesive to naps |03 and |04 and has formed threecrease lines dening the flaps so that the flapsV are A stop generally upwardly disposed.- Also upper blank |0I Vhas been placed in proper register on lower 4 blank |02 and in this condition the work is placed on platen 44 with the trailing edges of the blanks engaging bracket 52.

Vertical guide plates |05-I06 are mounted in adjusted, fixed positions a distance apart equal to the width of blank IOI plus the thickness of flaps |04. This positioning is important in order to get a tight fold around the edges ofthe upper blank. These guide plates are secured to laterally extending supporting plates |01 and adjustment isfeffected by loosening set screws |00.

The rear edge of the platen is shown at |09 and there'is Valso provided a rearward extension 99 of the platen which is spaced therefrom so as to expose the upper periphery of forward rollers |6 which is on substantially the same plane as the platen. If desired platen sections 44 and 99 may be formed in one piece with a suitable transverse 4opening for the rst lower roller. A fixed brush IIO mounted` in a Abracket III initially bends forward flap |03 downwardly. If there is any initial tendency for the forward sections' of the blanks to rise, there are restrained by a plate II2 carried by the swingable roller assembly and which in its lowered position is just above the work 43. f

The. novel contour of the folding membersA I I3 is amply shown in Figs. 89 and 6.A They arepjro .vided with curved descendingsurfaces I I4which initially bend opposed flaps |04 downwardly before they encounter the rollers, and with vertical walls IIS which provide a tight .fold ofthe flap over the edge of the heavy blank.. These members are mounted on platesl I5'which are pivoted at |I6 and they arev urged inwardly byv springs I I1. Inward movementis limited byv a set screw |20 which contacts' anxed stop I2I. After the finished article passesthe secondrollers it passes down chute |22;

The manner of placing' the superimposed blanks on the platen has alreadyl been described. Rollers i-6 and I1 are `continuously rotating. The foot treadle is nowdepressed and `roller 23 descends to the position shown in broken lines in Fig. 2 which urges the work into contact with roller I6 which drivesl the work forwardly where flapsv |03 Contact brush I I0, giving` it its initial fold. At about the time the leading edgeofl the work contacts rollers I1 and 22 the side folding members IIIi have begun their work of folding down flapsv |04: Any slight deviation from straight opposed edges of the workv causes the folding members to retract slightly although vertical wall I I9 isA always-'in firm contact with the edge. If continuous operation `of the machine is desired, it is onlynecessaryto tie down the foot treadle or the entire manual lcontrol maybe eliminated vand timing ofthe descent of the upperl forward roller is-arranged by varying the contour of cams 63 and 64.

While one form-orn embodiment of the invention has been shownand described hereinA for illustrative purposes, and the construction and arrangement incidental to one specicapplication thereof has been disclosed and discussed in detail, it is to be understood that the invention is limited neither to the mere details or relative arrangement of parts', nor to its specific embodiment shown herein, but that extensiveV deviations from the illustrated form or embodiment of the invention may -be 'made without departing from the principles thereof.
